You need to cut a 9 foot piece of plywood into 12 inch sections. Every cut also removes 1/8 inch. How much of the plywood will be left after cutting the 12 inch sections?
Answers
Considering this fact, each cut would take away 0.125 inches. If you're cutting 8 times, you would in all be taking away 1 inch.
So aside from the eight 12" sections, you would have a leftover of 11 inches.
11 inches of the plywood will be left after cutting the 12 inch sections.
What is Fraction?A fraction represents a part of a whole.
Given that we need to cut a 9 foot piece of plywood into 12 inch sections and every cut also removes 1/8 inch.
We are to find the quantity of plywood that will be left after cutting the 12 inch section.
We know that 1 foot = 12 inches.
So, 9 foot = 12 × 9 = 108 inches.
Since each cut removes 1/8 inch at ever cut, so the number of 12 inch sections will be 8.
Quantity of plywood that remained after cutting the 12 inch sections will be 108-12×8-8×1/8=11
Hence, 11 inches of the plywood will be left after cutting the 12 inch sections.

Chase answers 3/4 of his math questions correctly. There were 40 questions on the test.
a. How many did he get right?
b. How many did he miss?
Answers
A simple way to solve this is to add a zero to the end of each number in the fraction since there is 40 questions so it goes from 3/4 correct to 30/40 correct.
Hope this helps!!
Chase answered 30 questions correctly and missed 10 questions.
Explanation:To find the number of questions Chase got right, multiply the fraction of questions answered correctly (3/4) by the total number of questions (40):
Number of questions answered correctly = (3/4) * 40 = 30
To find the number of questions Chase missed, subtract the number of questions he got right from the total number of questions:
Number of questions missed = 40 - 30 = 10

Misha used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below: Color of Marble Number of Times Rolled Blue 20 Green 18 Yellow 12 Heads Tails 28 22 Using Misha's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
Answers
To solve this problem, let us first remember that probability is:
Probability = number of successful events / number of total events
Now, let us first calculate the probability of getting a blue marble. There are 20 blue marbles out of 50 total marbles, therefore the probability is:
P (blue marble) = 20 / 50 = 0.4
Next, let us calculate for the probability of landing tails up. There are 22 tails success out of 50 times the coin was tossed, therefore the probability is:
P (tails) = 22 / 50 = 0.44
Finally, since we want to find the Probability of getting blue and Probability of landing tails, we multiply the two:
P (blue and tails) = 0.4 * 0.44
P (blue and tails) = 0.176 (ANSWER)
Now if the choices are in fraction:
P (blue and tails) = (20 / 50) (22 / 50) = 440 / 2500
Answer:
The answer is 440/2500

Which expression could be used to determine the product of –4 and 3 1/4?
Answers
To determine the product of -4 and 3 1/4, multiply the whole numbers and the fractions separately, and then add the results together.
Explanation:The product of -4 and 3 1/4 can be determined by multiplying the whole number part, -4, by the whole number part of the mixed number, 3, and then multiplying the fraction part, 1/4, by the whole number part of the mixed number and adding the result to the previous product.
So, -4 × 3 = -12
and (-4) × (1/4) = -1
Therefore, the product of -4 and 3 1/4 is -12 - 1/4 = -12 1/4.
To find the product of -4 and 3 1/4, convert the mixed number to an improper fraction and then multiply.
Explanation:The product of -4 and 3 1/4 can be found using the expression:
-4 x 3 1/4
To multiply a whole number by a mixed number, you can convert the mixed number into an improper fraction and then multiply:
-4 x 13/4
Multiplying whole numbers and fractions can be done by multiplying the numerators and denominators separately:
-4 x 13 = -52
4 x 1 = 4
The final answer is -52/4, which simplifies to -13.
